Since Rimworld is using DX11 according to the log file, this appears to be a system running Windows 10.
Now, this "purple" (or magenta) image is the "fallback" shader that Rimworld (or perhaps the Unity engine) uses when a shader fails to load.
As-is, this appears to most commonly be caused by a graphics driver failure.

The newer 200-series drivers seem to have this type of issue with RimWorld, or perhaps the Unity engine.

My first suggestion would be to attempt to update to the newest driver for your graphics card.
http://support.amd.com/en-us/kb-articles/Pages/AMD-Radeon-200-Series-Drivers.aspx#win10

If the issue persists, you may need to uninstall the current AMD display driver and download an older version of the AMD display driver.
As per the instructions provided by another user that was having the same issue, also with a 200 series AMD card, the 16.12.2 driver (released 1/8/2017) should work.

ok well the old driver worked so what i cant ever update my driver now?

For whatever reason, the most recent set of AMD drivers are causing problems with Unity's shader support, as there have been multiple pink/purple screen reports now from AMD users. I'm not sure if this driver issue affects all Unity games or just some of them, but I doubt it's a RimWorld only issue.

Whether the fault rests with AMD, Unity, or both I do not know. But unfortunately, until one or both of the aforementioned parties address the issue at their end (most likely AMD), all we can suggest here is for AMD users to use an older driver for RimWorld and wait for the newer drivers to fix the problem (which I assume they will at some point, but only AMD know when and how long it'll take).

There might be an alternative solution for AMD users that allows them to use the newer drivers (such as using the AMD CP to force RimWorld to use such and such settings), but until someone posts an alternative then we only have the one solution to offer right now (which so far has worked for all the AMD users who've reported this problem recently).

[Robrogamer]

it probably is a problem with that driver though because i was having trouble with total war: warhammer too and it seemed to also resolve that issue.

[Calahan]

^ That's interesting, and from the PoV of AMD fixing this issue asap, it might be a good thing that a game like TW:Warhammer is having problems as well. Since Creative Assembly certainly have more capacity to pressure AMD into a speedy resolution than any small indie studio does, and I'd imagine if enough AMD users complain to CA then I'd assume they'd quickly chase the issue up with AMD (especially if it starts costing them sales/refunds).

Hi, am having the pink screen issue here, too.

OS is Win 10 1703 x64, AMD GPU Driver is version 17.5.2.
Rimworld version is 0.17.1546 rev882

Initialize engine version: 5.3.4f1 (fdbb5133b820)
GfxDevice: creating device client; threaded=1
d3d: no support for this device type (accelerated/ref)
GfxDevice: creating device client; threaded=1
Direct3D:
    Version:  Direct3D 11.0 [level 11.0]
    Renderer: Radeon (TM) RX 470 Graphics (ID=0x67df)

I can confirm that A15 starts normally, while A16 and A17 both start without shaders and therefore pink.

@ psannz - Have you tried installing an older AMD? (as mentioned earlier in the thread).

[milon]

If that doesn't work, uninstall the driver (& delete it when prompted) then reboot. Windows should automatically download the best match it can find, and you'll likely get a more generic driver that might give you better success.

Yes, older driver works. Buggered performance on newer games tho...
AMD driver version 17.10.1731 (17.4.4) is causing pink screens, too.

[sannz]

Rejoice!

AMD Driver 17.7.1 (17.10.3211; released 14.07.2017) runs Rimworld (0.17.1557) once again.

Awesome, glad to hear it!

This is good.
